4 Claims.

This invention relates to removable brush covers for cotton linters.

One object of the invention is to provide, in a cotton linter or machineof similar character for the treatment or processing of cotton, aconveniently located and quickly and easily removable and replaceablecover for the rotary brush element thereof, whereby access to the brushelement is readily gained when occasion requires, for adjustments,repairs, etc.

Another object of the invention is to provide a simple yet practical andefficient hood-like cover which permits the lowering of the supportingframe and housing portion of the machine in the region of the brushelement to a plane below the upper working portion of the brush element,whereby, upon removal of the cover, not only said element itself isexposed and conveniently accessible for adjusting and repairing it, ifnec- 0 essary, without necessitating its removal from its normalmounting in the machine, but access is also readily gained to every partof the working chamber in which the brush element is located.

A further object is to simplify the releasable fastening means for theremovable cover without taking from the requisite stability of thestructure.

A construction designed to carry out the invention will be hereinafterdescribed, together with other features of the invention.

The invention will be more readily understood from a reading of thefollowing specification and by reference to the accompanying drawing, inwhich an example of the invention is shown, and 5 wherein:

Figure 1 is a fragmentary side elevational View of a cotton linter inthe region of the brush element, showing a cover applied in accordancewith the invention;

Figure 2 is a transverse, vertical section showing the working relationbetween the brush element and cover when the latter is placed on themachine;

Figure 3 is a fragmentary perspective view of 45 one end portion of thecover detached; and

Figure 4 is a fragmentary section, on a somewhat enlarged scale, takenon or about the line 4-5 of Figure 1, to show details of the cover andmore particularly the fastening means therefor.

Refering now to the drawing, the numeral l designates the rear portionof a cotton linter machine in the region of the brush element 2, whichlatter is located in the working chamber 3 of the machine. The brushelement 2 is con- 55 ventionally shown as mounted on the usual shaft 4which is journaled in bearings 5 provided therefor on the side framemembers or housing walls of the machine. For the purposes of the presentinvention, the side frame members or housing walls of the machine arelowered, as at 6, to a horizontal plane preferably just above the axisof the shaft 4, as shown, or substantially even with the upper side ofthe shaft; and, to permit of readily placing and removing the brushelement 2, the side frame or wall members are cut away or notched, as atl, in order to provide working clearance as well as for the readyreplacement and removal of the shaft 4.

At the rear side of the machine frame or housing is a horizontal crossframe member 8, which, as shown, may be of angle iron cross section orsubstantially inverted L-shape. As shown more clearly in Figure l, theend portions of said frame member 8 are supported on counterpart seatportions 9 of the side frame or housing members of the machine and,obviously, there secured by welding or other approved or desirable meansof fastening, for example, screws, bolts or rivets. The means offastening of these, and other structural parts, however, does not enterper se into the present invention. Hence, the same is not shown indetail in the accompanying illustrative drawing.

Extending up from the cross frame member 8 are bracket frame members Inhaving foot portions ll of angular form corresponding to said framemember 8 on which they are securely fastened by any approved means, saidbracket frame members extending, as shown at l2 in Figure 1,horizontally with their upper portions projected towards the upper frameor housing portion I3 of the machine, to which they are joined, as atIt. The bracket frame members l0 brace the upper rear portion of themachine body frame or housing, and at the same time ample space isafforded between said members l0 themselves and between them and theadjacent body frame and housing side wall members for readily placingand removing the brush cover l5, now to be described, and facilitatingaccessibility to the brush element when uncovered and also to theinterior of the working chamber in which the brush element is located.

The cover 15, which, obviously, may be conveniently made of sheet metal,comprises the end walls It, said end walls, as shown, consisting of bodyplates reinforced at their marginal portions by angle members l'l,affording stiffening flanges thereabout.

Preferably, the rear upper portions of the end walls P3 are rounded, asat l8, and a top plate I9 is secured marginally, as at 29, to thereinforced flat upper and rounded rear marginal portions of said endwalls It, thereby producing a relatively light-weight yet rigid andstable hood-like structure to cover, when applied, the portion of thebrush element that protrudes above the lowered body frame or housingside wall portion 6 of the machine.

The cover l5, when applied, as shown, rests at each end on saidhorizontal machine frame or body portions 6 with the inner vertical edgeportions of the end walls i6 abutting the adjacent portions 2'2 of themachine frame or housing exending vertically upward from said horizontalportions 6, and to afford clearance for the brush shaft bearing 5 thehorizontal flange portions of the cover end walls are cut away, as at 23(see Figures 1 and 3).

The lower outer end portion of the cover i5 is placed between the footportions l l of the bracket frame members til, so that the cover is heldagainst shifting movement transversely of the machine body frame orlongitudinally with respect the axis of the brush element. To furtherprevent shifting of the cover 15, more particularly in a transversedirection, or, in other words, in a direction outwardly from its normalabutting relation to the vertical portions 23 of the body frame orhousing of the machine, and also to prevent accidental or unintentionallifting the cover, releasable fastening means is provided at each end ofthe cover. As shown, this fastening means comprises an ear or lug 2.5,rivetwelded or otherwise secured or provided on the end wall bottomreinforcing member I! near the outer side of the cover (see Figures 1,3, and i), said ear or lug 24 having a transverse openended slot 25 toreleasably engage a securing bolt that is applied therethrough andthrough an aperture obviously provided therefor in a horizontal flangedinward extension or shelf-like ledge El of the seat portion 9 of thebody frame or housing side wall of the machine where the foot portion ii of the br cket frame member It rests. By this provision the cover isobviously fastened in place by tightening the bolt 26 to clamp the earor lug 26 upon said flanged extension or ledge 21, yet the cover isreadily removable by merely loosening the bolt 26 and moving the coveroutwardly and thereby withdrawing the slotted ear or lug member 24 fromongagement with the bolt, it being, of course, understood that a similarfastening means is provided at opposite ends of the cover.

In order to further reinforce the cover l5 which, of course, toaccommodate the brush element, is open at its bottom and inner side, andparticularly to strengthen and make more rigid the outer lower marginalportion thereof, an angle bar or flange element 28 is preferably securedthereto on the outside, as shown.

Cbviously, the structure and particular arrangements of the parts of thedevice relative to each other and in each particular adaptation of theinvention in practice may be modified in many respects within the scopeof the appended chums. The invention as defined, therefore, is

not limited to the specific construction and arrangement of theaccompanying illustrative drawing.

What I claim and desire to secure by Letters Patent, is:
